Can't init ComputeEngine using iPhone SE

[truebluepl]

Description

I can't init ComputeEngine object.

Steps to Reproduce

let ce = new ComputeEngine();
via MathField object CE is not accessible also.

Actual Result

CE 0.24.1
SyntaxError: Invalid regular expression: invalid property expression at line 3880
var ONLY_EMOJIS = new RegExp(^(?:${POSSIBLE_EMOJI})+$, "u");

CE 0.26.4
ReferenceError: Can't find variable: BigInt at line 6287
BigInt(2),

CE 0.24.1 and CE 0.26.4
TypeError: Object is not a constructor (evaluating 'new ComputeEngine()')
let ce = new ComputeEngine();

Expected Result

CE object should be created.

Environment

I tested using iPhone SE 2020/iOS13/Safari (at BrowserStack.com).

[arnog]

The issue is probably not the iPhone SE but rather iOS 13, released in 2019.

Obsolete, no longer receiving security updates, because all iPhones and iPod Touches that supported iOS 13 support iOS 14 and iOS 15 as well.
